T1 board issues

For some reason, the LCD is very troublesome. When I got the gun, the display was all messed up and only a fraction of the pixels would show. After cleaning it, it started to work again but as soon as I put it back in the gun, it went back to its old ways.

So I've set my board up with a few LED's to display basic functions, I've got an on/off, a button depression indicator (covers both buttons) and a safe mode indicator. Does any one know how I can make an indicator for ROF, shot counter, timer or Dwell adjustments? I mainly only need Dwell adjustments.
